# This BUILD_CONFIG option is a bit like bootstrap-debug, but rather# than comparing stripped object files, it compares compiler internal# state during stage3. Both can be used simultaneously.# This makes it slower than bootstrap-debug alone, for there's# additional dumping and recompilation during stage3.# bootstrap-debug-big can avoid the recompilation, if plenty of disk# space is available.STAGE2_CFLAGS += -fcompare-debug=
